.This invention relates to splash troughs forinternal combustion engines and hasy for its object the provision of means whereby theva'rious instrumentalities of which ,the

' the scope of the appended claims...

the sediment in the oil may' be` collected and withdrawn 'from all ofthe troughs siniultaneously without disturbing the 'troughsor securing access to the interior ofthe casing.

These objects are obtained by themech'aiiism illustrated inthe accompanying drawl:

ings.

For the purposeot illustrating the inveiition one preferred `form, thereof is illusvtrated 4in the drawings, this Vform having been found togive satisfactory Vaiid'reliable results althoughit is tofbe understoodithat invention consistsY can bevariously arranged and oi'ganif/.ed-.and the invention is not limited to the precisel arrangement and organi-k zation ot these instrumentalities as herein..

shown anddescribed exceptas required by Ot the drawings:

Figure 1 represents a vertical transversev section o'ffa crank casm'gprovidedrwith a plurality of splash troughs and a sedimenty removing device embodying the principles of the present invention. f

Figure 2 represents a vertical seotionof the same on line 2, 2 on Fig. 1, and

Similar characters VVindicate like parts'k throughout ings.

In the drawings, 10 is a crank casing protlie several 'figures of the drawvided with a plurality of splash troughs 11,

each having an -oil-containing compartment 12 contained therein. Y

The usual crank 13 is mountedV upon a revoluble shaft 14 pivo'tally connected at its outer ends to a connecting rod 15.

As the shaft 14 revolves the pivotal con` nection between theouter end of the crank 13 and the connecting rod 15 Vsplashes through the oil'contained` in the compartfment 12 and is thoroughly lubricated. Y

In thedrawings the splash A troughs are shown'as formed integralwith the casing 1() which 4is provided with a bottom 16.

Each oil trough 11 hasa downwardly' Aprojecting lug 17 in which vis formed a cylindrical chamber 18, the chambers 18 represents an elevation 'of onef threaded lug'29. f'

Ifdeslred only one of the v closures 27 the f .may be removedv and a pump yattached to the Y yopen end of the tubular member'QOwand the sediment may then be drawn from the bore thereof. Y y

As soon as the tubular member has been'cleared of its sediment, the closures `27 are again positioned on the endsY of said member andthe arm 24 moved into contact Y with the stop member 26, vand secured in this position'by the bolt 25. Y This makes a very simple device for removing. the sediment from splash troughs and one which may be operated very quickly so that the engine may be maintained in comvmission at alltimes. Y

It does away with the necessity of dis` mantlingthe crank casing in order -to gain accessfto the oil troughs When it is desired to remove the L,sediment therefrom. i

AThis is a ygreatV advantage particularly When the `enginevis mounted upon` av fireV truck which is liable to be called for duty at Vany moment.

It is believed-that the operation andinany 7 advantages ofthe invention will be underthereof iiormally registering with*l said discharge opening; means foroscillating said pipe ;V Yand removable Vclosures for theopposite ends of said pipe.
